Read the first 7 Installation Practices & Standards flashcards as text

  1. What is the correct polarity of DC voltage applied over coax to power an LNB and select vertical polarization on a linear polarization system?

    Answer: 13V DC

    13V DC applied over the coaxial cable selects vertical polarization on a linear LNB, while 18V selects horizontal polarization.

  2. When installing a satellite dish in a high-wind coastal area, which mounting configuration provides the greatest structural stability?

    Answer: Ground-mounted concrete base with embedded pole

    A concrete-embedded ground mount provides the most rigid, wind-resistant foundation and is preferred in high-wind or coastal environments.

  3. According to FCC regulations, who is responsible for ensuring that a satellite receiving system does not cause interference to other users?

    Answer: The installation technician and system owner

    FCC Part 25 places responsibility on the licensee/system owner and, by extension, the installation technician to ensure the system operates within regulatory parameters.

  4. What is the maximum distance a ground rod electrode can be from the building entry point for the grounding conductor to remain compliant under NEC 810?

    Answer: The conductor must be as short and direct as possible with no stated maximum distance

    NEC 810 requires that the grounding conductor be run as short and straight as practicable, but does not specify a maximum distance — minimizing conductor length is the goal.

  5. A customer reports intermittent satellite signal loss during rain. The dish alignment was verified to be correct. What is the most likely cause?

    Answer: Rain fade affecting the satellite uplink or the signal path

    Rain fade occurs when precipitation absorbs and scatters microwave signals in the path between the satellite and the dish, causing signal attenuation.

  6. When using a cable stripper to prepare RG-6 for an F-connector, what portion of the cable dielectric (foam insulation) should be exposed?

    Answer: 3/8 inch

    Proper RG-6 preparation exposes approximately 3/8 inch of center conductor and dielectric to correctly seat inside most compression or crimp F-connectors.

  7. Which SBCA installation standard addresses the requirement for a technician to verify 'clear line of sight' before finalizing a dish mounting location?

    Answer: SBCA STD-0101

    SBCA STD-0101 covers residential satellite system installation standards, including the requirement to confirm unobstructed line of sight to the satellite arc.
